Application niednovember 14, 192s. serial No.. 319,227.

My invention relates to vnew and useful improvements in a cooler for stills and hasv for one of its objects to provide an exceedingly simple and effective device of this character in which the heat transfer elements or the distributor and the chamber containing. they distributor may be easily and quickly cleaned.

Another object of the-invention is to provide the construction of the cooler in which The cooler such. asherein` contemplatedmay i be used for the `distillation of water, alcohol, oils and acids', and I have found thatl in the distillation of some of these, particularly.l certain of the acids, it is' necessary to use very expensive metals for the parts through; which the acid elements pass, such as: gold andsilver. By constructing the parts as herein shown, a very substantial. saving inf metal is accomplished thereby reducing: the .costof manufacture.l Further, by making' theparts removable, theyv maybe disassembled and cleaned after each run. and the lgusirtsL easilycleaned to remove any residue.l or clean.` out oxidation whichk might bei detrimental'to the next substance to be distilled'.`

With the above: in mind it is'A one of the obf' 401 jects to provide a chamber forv the reception of water in circulation, said chamberhaving a barrel ypassing therethrough to provide a condensing chamber, the latterxhaving a ,re-E

movable vapor distributing means` therein exemplified by a perforated tube'.

With these ends in view, this invention consists-in the details'of. construction and combi-lv nation of elements hereinafter set forth and then specifically` designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will deunderstood. f

scribe its construction in detail, referring by numerals to thev accompanying drawings forming a part ofy this application, in

which :--l f Fig.k 1, is a longitudinal sectional'viewvof a cooler' constructed in accordance with my invention, some of the partsbeing left in elevation and showing its connection `with afstill andan outlet conduit. i l i i 5 Fig. 2, is a section at the line 2 2 ofFig. 1. In carrying out my invention as herein 'em- -f bodied, 8 representsa still of any ordinary or 'deslrable construction which is heatedin the usual manner to change the liquid or Huid contentsv into a vapor, the latter being carried off through a suitable conduit or goose neck 4L The outer end of the goose neck is detach-- ably connected to one end` ofthe cooler 5 by .means of a suitable union nut' coacting with the flange 7 on the goose neck and having threadedy connection as at 8 with one of the reduced ends of the barrel9.

Both endsof said barrel are'reduced in diameter relative to the intermediate or major portion thereof so that-the ends of the tubular distributor 10` will snugl fit in said reduced end-sof'thebarrel while t e intermediateportionzof said tubey will'be spaced from the intermediate portion of the barrel, thus providing a `condensing chamber 1.1. The tube 10 is :heldin-place ati one end by the union nut 6 and at the other end bythe cap 12 having threaded engagement withy thev outery end4 of. the barrel 9 and said-cap also acts as a closure forfbothithe' tube and barrel aswill be vreadily The` tube 10` isf provided. with any number of perforations 13, but these are preferably so arrangedk or located that'they lgradually increase innumber toward the outer end of the tube and' some yof .the ones nearer the outer end are at higher elevations than the-other ones. This arrangement prevents the vapor yleaving the tube all at' one yend, or inother words, the particular arrangement of the-apertures causes-the vapor/to be distributed. to the-condensing chamber.' ati different points. Of course the size of the apertures will also govern this to some extent as will be obvious.

v The condensation accumulating in the condensing chamber 11 will flow off to a point of disposal through an outlet conduit 14 convided with a trap 15 to prevent escape of any vapor prior to condensation. i l

Surrounding the major intermediatefportion of the barrel is a tank, receptacleor con-.. tainer forming a watercooling chamber I17 .A and the wallsof this container have `r'water tight joints with the barrel 9, outletconduitj 14 and any otherpipes which may pass through or be connected therewith! Water4 or any other cooling medium is circulated through the 'cooling f chamber by `means of an inlet pipe 18 provided with a perforated header 19 and an outletspipe 20.' The inlet pipe 18 leads vto the header which is'located adjacent itheibottom of! the cooling chamber so that'the cooling medium will flow into the bottom'of said coolingfcliamber and as it becomes heated it will rise to the top of saidI chamber and pass off through the outlet 'F rom the foregoing description, 'it will be noted that wheny the contents ofthe still are vaporized,the vapor will theniiow'into the distributor s10 andvpass therefrom at different point-s through the perforations 13 into the condensing chamber 11y being condensed'by the low temperature of said chamber'due to 1 the How of a coolingr medium thereabout within thefcooling chamber 17 andas the condensation takesV place, the contentswill flow od through the outlet pipe 14to any suitable point of disposal. n v

After the distilling operations havel been completed, either vtheunion nut 6 or the cap tor disassembled so that the condensing chamreadily cleaned.

berand the inner walls of the barrel 9r and the distributor both 'inside andV outside may be It is' to be particularly n'otedtliat` the barhas taken place. ra. Y

There are two pointstolwhich Ivfdesire tovu call attention, the first and foremost lone being the-ease with which the parts of the cooler f may be readily cleaned and the other is the small amount of metal necessary :to produce the `barrel andv distributor.;

. Of course Ido not Wish to be limited tothe y exact details of construction asherein shown, as these ymay be varied within the' limits of;

the appended claims without departing from the spirit of my invention.

Having thus fully described my invention, whatI-:claim as new and useful is 'cool'erfor-stills-consisting of a con* tainer to .provide a chamber for the circulation ofa f :oolincV medium, .a barrel mounted withinthecntainer andhavi'ng' its ends proejetingtherefrom, a distributor removably mounted within said barrel, means to detach- .1: ablycconnectthe' outlet of a still with one end of said distributor, and means for carrying off the condensate fromthe barrel. 1
